The so-called snoring is air impact narrow airway, causing pharyngeal soft tissue vibrations emitted sound. Sleep muscles in a relaxed state, will be slightly smaller than the pharynx when sober, to a certain extent if the pharyngeal stenosis, airflow will cause vibration local mucosal tissues, resulting in sound. Slight, even snore, snore occasionally, or due to other causes of poor sleep posture, not much harm to the human body. However, once the airway to narrow or even more serious degree of obstruction, snoring can affect the respiratory air flow, the air flow is reduced or stopped breathing, harm the big sleep during recurrent airway obstruction, can not breathe properly, can appears to reduce the oxygen content in the blood, increased carbon dioxide, causing increased heart rate, increased blood pressure, vascular wall damage. If the blood oxygen content is reduced to a certain extent, the body will start the “protection” mechanism, by waking brain, forcing issued a directive to make the muscles work to expand the airways, thus unblocking, this mechanism prevents the oxygen content in the blood is too low lead to danger, but it also interferes with the normal sleep process. Sleep is a physiological process that people must be carried out daily by sleep can restore physical and mental. Sleep is an iterative process consisting of different stages and at different stages of sleep is responsible for the completion of different physiological functions. If you repeatedly disturbed sleep, cause sleep disordered structure, leading to daytime sleepiness, fatigue, difficulty concentrating, memory loss and other symptoms, or even depression, restlessness, irritability and other personality changes. If sleep apnea is not a normal phenomenon frequency exceeds a certain limit, it can be defined as a sleep breathing disorders. On the one hand, this disease can increase the risk of high blood pressure, the risk of cardiovascular disease or diabetes; on the other hand, with age and weight gain, the disease can be more serious. If sleep is always to reduce oxygen, the body gradually tolerate low oxygen state, the body wake up the brain’s “protection” mechanism will be more sensitive. Over time, protecting the body against low blood oxygen backward, even if there is no low oxygen reduction reaction, when it exceeds a certain limit, the body is very dangerous, there are likely to be directly transferred to cerebral edema and suffocation. Therefore, early treatment is essential.
